About hardware and software requirements
This table summarizes the hardware and software requirements for the appliance.
Component | Requirements |
|---|
Storage | Power-failure resistant RAID Controller with at least 512 MB of NVRAM, either super cap or battery backed. At least two HDD drives that are exported by the RAID controller as a single RAID 1/10 volume. At least two SSD drives that are exported by the RAID controller as a single RAID 1/10 volume. |
VMware-certified server hardware | ESXi version 7.0 Update 3 or later. System chipset must support VT-D/X (Intel’s device-level virtualization). Installation disk: a separate drive with at least 16 GB to install ESXi (SDHC, flash, or M2 SATA port). |
Network | One network interface of at least 100 Mbps. Three network interfaces of at least 1000 Mbps. Two-port to four-port Riverbed bypass network interface card (NIC), or two to four additional network interfaces for virtual in-path configurations. |
Memory | In addition to the memory required for Edge, there should be additional memory for customer virtual machines. |
CPU | In addition to CPU required for Edge, there should be additional CPU cores for customer virtual machines. |
Supported bypass cards | NIC-001-2TX (2 port copper) NIC-002-4TX (4 port copper) |
Virtual machine | 6 CPU cores 48 GB memory 5765 GiB datastore, includes space for virtual Edge and blockstore virtual machine disks (VMDK). |
Technical specifications | Blockstore: 5000 GB Read cache: 500 GB Write-back cache: 50 GB Segstore: 280 GB |
Hardware recommendations
Follow these hardware recommendations for optimal performance:
• Do not share physical NICs—For optimal performance, assign a physical NIC to a single LAN or WAN interface. Do not share physical NICs destined for LAN/WAN virtual interfaces with other VMs running on the hypervisor. Doing so can create performance bottlenecks.
• Ensure that the host has resources for overhead—In addition to reserving the CPU resources needed for the Edge model, verify that additional unclaimed resources are available. Due to hypervisor overhead, VMs can exceed their configured reservation.
• Do not overprovision the physical CPUs—Do not run more VMs than there are CPUs. For example, if a hypervisor is running off a quad-core CPU, all the VMs on the host should use no more than four vCPUs.
• Use a server-grade CPU for the hypervisor—For example, use a Xeon or Opteron CPU as opposed to an Intel Atom.
• Virtual RAM should not exceed physical RAM—The total virtual RAM provisioned for all running VMs should not be greater than the physical RAM on the system.
• Do not use low-quality storage for the RiOS data store disk—Make sure that the Edge disk used for the data store virtual machine disk (VMDK) resides on a disk medium that supports a high number of Input/Output Operations Per Second (IOPS).
• Do not share host physical disks—To achieve near-native disk I/O performance, do not share host physical disks between VMs. When you deploy Edge, allocate an unshared disk for the RiOS data store disk.
